My cellular phone can take pictures although it sees practically no use.

I also have a disposable film camera in the gloves compartment of my car since ages, that's for the case of car accident, I think in case I would use the camera in my cellular phone instead, but there's no need to remove the camera from there. This very evening somebody broke into my car (damaging the lock but not breaking the glass, thank goodness) and did not take the disposable camera, see where we have arrived.

I miss the smell of instant film, which would bring me back to when I was 15 years old, and the next fit of insanity will probably result in some sort of instant camera just for the smell of it

PS God save me from the temptation of trying medium format!

PPS I advice to make a list of all your photographic gear (camera, lenses, flashes, light meters whatever) and take a note of each and every serial number. This can be useful in case of theft.
